Finding Slope HELP ME PLS

Answers

Answer 1

Answer:

-3 because (-1,-7) and (1,-13) takes -6 to get from -7 to -13 and 2 to get from -1 to 1. -6/2 is -3, so the slope/answer is -3.

Step-by-step explanation:

Answer 2

Answer:

Formula for finding slope is given as y2-y1 ÷ x2-x1 or y1-y2 ÷ x1-x2, where x and y are the coordinates of the points.

Slope = -13-(-7) ÷ 1-(-1)

= (-13+7) ÷ (1+1)

= -6 ÷ 2

= -3

1) The table represents the relationship between a length measured in meters and th same length measured in kilometers. a. Complete the table. meters kilometers 1,000 1 3,500 500 b. Write an equation for converting the number of meters to kilometers. 75 1 X

Answers

Explanation:

1)

1 kilometer is equal to 1000 meters:

1 km = 1000 m

So,

1m = 1/1,000 km

To complete the table, we can use the rule of three:

a) 1,000 m?

1m - 1/1,000 km

1,000m - x

x = 1/1000 * 1,000 = 1 km

As we can see, we only have to divide the measure in meters by 1000.

b) 3,500 m = 3,500/1,000 = 3.5 km

c) 500 m = 500/1,000 = 0.5 km

d) 75 m = 75/1,000 = 3/40 km = 0.075 km

e) 1 m = 1/1000 = 0.001 km

f) x = x/1,000 = 0.001x km

2)

The relation is:

Y = 0.001x

Where x is the measure in km and x in meter.

Are your finances, buying habits, medical records, and phone calls really private? A real concern for many adults is that computers and the Internet are reducing privacy. A survey conducted by Peter D. Hart Research Associates for the Shell Poll was reported in USA Today. According to the survey, 43% of adults are concerned that employers are monitoring phone calls. Use the binomial distribution formula to calculate the probability of the following.

Answers

The probability of matching x successes on n further trials in an experiment with two possible outcomes. There is a 4.88% chance that no one is worried that their employers are listening to their phone calls.

Given that,

The probability of matching x successes on n further trials in an experiment with two possible outcomes is known as the binomial probability (commonly called a binomial experiment).

The following formula gives it:

[tex]P=C_{n,x}p^{n}.(1-p)^{n-x}[/tex]

Where is the number of distinct combinations of x items drawn from a set of n elements, as determined by the formula below.

[tex]C_{n,x}=\frac{n!}{x!(n-x)!}[/tex]

And p is the probability that anything will happen.

Being aware that employers are monitoring phone calls is a victory in this issue.

43% of adults fear that their employers are listening to their phone calls,

p=43%=0.43

We must locate Four persons were questioned, and none expressed concern about phone call monitoring by companies.

We count four adults, n=4.

Is there a probability of success of 0? If so, then x = 0.

[tex]P=C_{n,x}p^{n}.(1-p)^{n-x}[/tex]

[tex]P=C_{4,0}(0.43)^{0}.(0.57)^{4}[/tex]

P=0.0488

Therefore, There is a 4.88% chance that no one is worried that their employers are listening to their phone calls.

Graph 1(90°,0)(FGHJ).Which graph below shows the preimage FGHJ and the image F'G'H''?

Answers

Given the figure FGHJ with coordinates

F(0, 5), G(-5, 1), H(5, -7) and J(6, 4)

When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure.

Therefore, for clockwise rotation, the coordinates of the image of FGHJ becomes

Solve using proportions.
Andrew is on a low-carbohydrate diet. If his diet book tells him that an 8-oz serving of pineapple contains 19.2 g of carbohydrate,
how many grams of carbohydrate does a 5-oz serving contain?

Answers

Using proportions we know that a 5-oz serving contains 12g of carbohydrates.

What are proportions?A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls, and 0.25 are males (by dividing 1 by 4).


So, the carbohydrates in a 5-oz serving:

The given proportion is, 8:19.2g.We need to get, 5:xg.

Now, calculate as follows:

8:19.2g = 5:xg8/19.2 = 5/xg8xg = 19.2(5)8xg = 96xg = 96/8x = 12g

Therefore, using proportions we know that a 5-oz serving contains 12g of carbohydrates.

Find Point F so that angle ABC is = to angle DEF

Answers

Answer

(5, 2)

Step-by-step explanation

Point D in triangle DEF is the equivalent to point A in ABC. Similarly, E is the equivalent to B. In consequence, F is the equivalent to C.

We can obtain points D and E by translating points A and B 6 units to the right and 4 units up.

Translation 6 units to the right and 4 units up transforms the point (x, y) into (x+6, y+4). Applying this rule to point C:

C(-1, -2) → (-1+6, -2+4) → F(5, 2)

A woman borrows #20 000 for 4 weeks. She agrees to pay #25 000 back at the end of the 4 weeks. How much interest does she pay over the a 4 weeks? b How much interest does she pay per week?how to solve ​

Answers

The interest she pays over 4 weeks is #5000 and the interest she pays per week is #1250.

According to the question,

We have the following information:

A woman borrows #20 000 for 4 weeks.

She agrees to pay #25 000 back at the end of the 4 weeks.

Now, we will subtract the borrowed amount from the amount paid after 4 weeks to find the interest paid after 4 weeks.

(a) Interest paid over 4 weeks = #(25000-20000)

Interest paid over 4 weeks = #5000

(b) Now, we can easily find the interest paid per week by the interest paid over 4 weeks by the total number of weeks.

Interest paid per week = Interest paid in 4 weeks/4

Interest paid per week = 5000/4

Interest paid per week = #1250

Hence, the answers to part a is #5000 and the answer to part b is #1250.

Find x and the measure of angle 1

Answers

The measure of angle 1 is 42° . Angles Central angles can be expressed as Central angle = (Arc length 360o)/(2r) degrees or Central angle = Arc length/r radians, where r is the radius of the circle.

What is meant by angle?When two straight lines or rays intersect at a common endpoint, an angle is formed. An angle's vertex exists as the familiar point of contact. Angle is derived from the Latin word angelus, which means "corner." An angle is formed when two line segments are joined at a single point, or when two line segments meet at a common endpoint. This common point is known as the angle's vertex, and the two line segments are known as the angle's sides or arms. Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle, and full rotation are the names of basic angles. An angle is a geometrical shape formed by connecting the ends of two rays.

Mary has scored 78, 60, 82, 94, and 88 on her previous fice tests.

What score does she need on her next test so that her average (mean) is 80?

Let x be the next test score

Recall that the mean is given by

[tex]mean=\frac{\text{sum of test scores}}{total\text{ numbers of tests}}[/tex]

We have the following information,

mean = 80

sum of test scores = 78 + 60 + 82 + 94 + 88 + x = 402 + x

total number of tests = 6

So, let us substitute these values into the above formula

[tex]\begin{gathered} mean=\frac{\text{sum of test scores}}{total\text{ numbers of tests}} \\ 80=\frac{402+x}{6} \\ 6\times80=402+x \\ 480=402+x \\ 480-402=x \\ 78=x \\ x=78 \end{gathered}[/tex]

Answers

a. $157.67

Explanation:

>> net income (total amount without the taxes etc...)

. biweekly = $575.50

. per month = $575.50 * 2 = $1,151 (~since it happens 2 times per month)

. per year = $1,151 * 12 = $13,812

>> gross income (total amount with the taxes etc...)

. per year = $17,500

>> amount deducted (~going to taxes etc...)

. per year = $17,500 - $13,812 = $3,688

. per month = $3,688 / 12 =~ $307.33

. per paycheck = $307.33 / 2 =~ $153.67
